If you've built production systems inside a DSP, an ad platform, or an ad tech company and know how pixels and conversions actually work under the hood, this is a senior seat where you'll own real architecture decisions on a small team that ships fast.\nPlease note: this role is a US-based role only and we cannot offer visa sponsorship for this role at this time.\nWhat You'll Do\nBuild and ship core product\nDesign, build, and ship backend services and APIs that power mate's agents, from spec to production\nImprove and maintain an identity graph.\nOwn features end to end, partnering with product and design on what to build and how\nWrite clean, well-tested, production-grade code and set the standard for the rest of the team\nAd tech infrastructure\nBuild and maintain our pixel, tags, and server-side tracking, and the conversion integrations with Meta, TikTok, Google, and others\nBuild integrations with DSPs, ad platforms, and partner APIs\nBuild the real-time services that deliver offers across the network, fast and reliably\nArchitecture and reliability\nMake architecture calls on how our systems scale: service design, storage, queues, and caching\nOwn reliability in production: monitoring, alerting, debugging, and incident response\nImprove developer tooling, CI/CD, and pay down tech debt where it slows us down\nEngineering leadership\nLead design reviews and code reviews, and mentor other engineers\nHelp shape engineering practices and hiring as the team grows\nRequirements\nWho You Are\nYou've built ad tech from the inside and know how the pieces connect, from pixel to conversion.\nYou like owning a system end to end, not just a ticket queue.\nYou're pragmatic: you ship fast on a small team without cutting corners on quality.\nYou think about the brand's outcome, not just whether the code ships.\nYou raise the bar for the engineers around you.\nWhat You Bring\n6+ years building and shipping production software, with meaningful time at an ad tech company (DSP, ad platform, ad exchange, or identity provider)\nStrong backend engineering skills in Python and Typescript, including designing APIs and distributed services\nHands-on experience building pixels, tags, SDKs, or conversion tracking, client-side and server-side\nExperience building systems that handle high request volume with low latency\nComfort with cloud infrastructure, containers, and CI/CD \nA track record of owning systems in production, from launch through monitoring and on-call\nBonus: Identity resolution / graph networks, ecommerce or Shopify, or early-stage startup experience.\nWhy This Role Matters\nMate only works if the systems underneath them are fast, reliable, and plugged into the ad platforms brands already buy on. This engineer builds that foundation. Get it right and brands see clearer results, buy more effectively, and spend more with us.
